. This inventionV relates to a darning' needle, especially for'mendingladders in stockings, which is provided, at itsanterior extremity, witha'hook.

This needle is characterized by an oscillating member rotatably mountedlin a recess provided in the body of the needle and intended to occupytwo positions, said oscillating'member being pro'- vided with a nose, aprojection and a main body, said nose being situated, when saidoscillating member occupies its iirst position, on the way or everythread sliding along the needle towards the hook, the projection beingthen hidden in said recess, while, when said oscillating member occupiesits second position, the projection obturates the mouth of the hook andthe nose is hidden in the recess, said main body extending along thebody of the needle when said oscillating member occupies its iirstposition, in such a way that a thread bearing upon it urges to hold saidoscillating member in its first position.

The annexed drawing shows, by way ofexample, one embodiment oftheinvention.

Figure l is a longitudinal section of a needle along line I--I in Figure2, the oscillating member being in its rst position.

Figure 2 is a section along line II-II in Figure l.

Figure 3 is a section similar to that oi Figure 1, but the oscillatingmember being in its second position.

Figures 4, 5, 6 and 7 show the process of a mending work, in severalphases.

The body of the needle is designated by I; it is constituted by a sheetof metal bent in such a way that the right section of this body has theform of a U, the sides of which are designated by Ia and the transversalpart of which is designated by Ib. A recess I3 is provided between thesides la. The needle is ended, at its anterior extremity, by a hook. Anoscillating member 3 is disposed between the sides Ia of the body I.Said member is oscillatably mounted on a pin 4 secured to the sides la.It comprises three parts: a nose 3a, a projection 3b and a main body 3c.The nose 3a has the form of a hook which is situated, when the member 3occupies its first position, on the way oi every thread sliding alongthe needle, in the direction shown by the arrow 5, for entering into thehook 2. The projection 3b is then hidden in the recess I3. During thisdis-` placement, the thread catches obligatory the nose 3a and drivesthe member 3 in rotation for bringing it into its second position, inwhich the projection 3b obturates the mouth of the hook 2. When themember 3 occupies its first position, its

2 main body 3 extends along the body I of the needle. The edge 3d ofthis main body projects out of the body I in such a way that a stitchbearing: upon itv urges to prevent the member 3 from going from. itsfirst position into itsfls'e'cond position. A notch isprovidedfin theVsidesl. This notch has for objectY to slow' the advance of the stitchalong the needle.. The member 3 is ended by a shoulder 3e intended toprevent a thread from going up along the needle beyond the body 3C. Ahole l provided in the oscillating member 3 is intended to lighten saidmember. 8 designates a solid bar situated between the sides la andriveted at 9. This bar ensures the rigidity of the posterior part of theneedle and constitutes a handle. The hook 2 is made thinner at IIJ,slightly under the axis of the needle, so that the thread situated inthis hook occupies this thin place Iii, what makes easier the operationof the needle.

This operation is the following:

The needle is introduced in a stitch II, ready to be dropped, under thelast stitch which has already been dropped, designated by I2. The stitchII abuts against the projection 3b and brings the member 3 into itsfirst position. It is necessary to drive the needle rather deeply sothat the stitch l I reaches at least the notch 6 it may even reach thebody 3c of the member 3; during this movement, the thread l2 came behindthe nose or hook 3EL (Figure 5). The needle is then pulled out. Thethreads I I and I2 slide simultaneously along the body of the needle, inthe direction of the hook 2. The thread I2 enters into the hook 3e(Figure 6). The member 3 is prevented from oscillating by the stitch IIwhichvbears on the edge 3d of the body 3C. A certain tension of thethread I2 then takes place. As soon as the stitch II has passed thebottom of the notch 6, the member 3 is released and occupies rapidly itssecond position, the hook 3a entering into the recess for hidingtherein. This hook 3a leaves then the thread I2 which is situated at themouth of the hook 2 and is thus obliged to enter into it. The tension ofthe thread I2 prevents it from leaving prematurely the hook 3a. Duringthe rotation of the member 3, the projection 3b passes before the stitchII and obturates the mouth of the hook 2, so that the stitch II leavesthe needle (Figure 7). If the thread I2 had accidentally not enteredinto the hook 2, the member 3 had not begun to rotate and it would bethe stitch II which should have entered into the hook 3a and then intothe hook 2 (Figure 4). The operation should have to be done again, butthe stitch Il should not have been dropped.

The stitch Il thus cannot leave the needle before the thread l2 hasentered into the hook 2.

In all the needles known up until today, the most frequent wrongoperation, viz. the noncatching of a thread, produces the outlet of thethread out of the needle and consequently the dropping of the justformed stitch and generally of several other stitches;

The needle does not present this drawback and can be operated withoutentailing an apprenticeship. A wrong carried out operation has simply tobe repeated, without the work precedently carried out being disturbed.

What I claim is:

In a darning needle, especially for mending ladders in stockings, endedat its anterior extremity by a hook, a body of this needle, a recess insaid body, an oscillating member rotatably mounted in said recess andintended to occupy two positions, said oscillating member being providedwith a nose, with a projection and with a main body and said oscillatingmember being arranged in such a way that when it occupies its firstposition, said nose is situated on the way of every thread sliding alongthe needle towards the hook, and the projection is then hidden in saidrecess,

while, when said oscillating member occupies its second position, theprojection obturates the mouth of the hook and the nose is hidden insaid recess, said main body extending along the body oi the needle whensaid oscillating member occupies its first position, in such a way thata thread bearing upon it urges to hold said oscillating member in itsrst position, the main body of said oscillating member ending by ashoulder intended to prevent the thread bearing upon said main body fromgoing up along the needle beyond said main body.
